Ratio of present age of A B and C is 4:6:7 respectively after 8 years ratio of age of a two age of B is 5:7 find the present age of c

Answer»

LET the present ages be 4x,7x,9x

then the respective ages 8 YEARS ago will be,

4x−8,7x−8 and 9x−8

According to the question

4x−8+7x−8+9x−8=56

20x=80

x=4

their present ages are,

4x=4×4=16years

7x=7×4=28years

9x=9×4=36years
